Procedure

To 171 mg of N-[2-(3,5-dichloropyridin-2-yl)-2-[1-(4-fluorophenyl)ethoxyimino]ethyl]-2-(trifluoromethyl)benzamide in 3 ml of acetonitrile, 1 mg of benzophenone was added, and the mixture was irradiated with light for 12 hours in a quartz cell (manufactured by Fine, 4 clear windows for spectroscopy) using a 100 W high-pressure mercury lamp (manufactured by USHIO INC., lamp: UM-102, power supply: UM-103B-B). After completion of the reaction, the solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography using ethyl acetate-hexane (with a gradient of from 5:95 to 50:50) as the eluent to obtain 98 mg of the desired product as a pale yellow resinous substance.
